16.4.2.5.5 Event Enable Register (EER)
The EDMA3CC provides the option of selectively enabling/disabling each event in the event register (ER)
by using the event enable register (EER). If an event bit in EER is set to 1 (using the event enable set
register, EESR), it will enable that corresponding event. Alternatively, if an event bit in EER is cleared
(using the event enable clear register, EECR), it will disable the corresponding event.
The event register latches all events that are captured by EDMA3CC, even if the events are disabled
(although EDMA3CC does not process it). Enabling an event with a pending event already set in the event
register enables the EDMA3CC to process the already set event like any other new event. The EER
settings do not have any effect on chained events (CER.En = 1) and manually set events (ESR.En = 1).
The EER is shown in Figure 16-65 and described in Table 16-44.

Bit Field Value Description
31-0 En Event enable for events 0-31.
0 Event is not enabled. An external event latched in the event register (ER) is not evaluated by the
EDMA3CC.
1 Event is enabled. An external event latched in the event register (ER) is evaluated by the EDMA3CC.
